Glentress in the Scottish Borders has a selection of different graded trails to suit most people. On the trail map you can see the network of routes and their grades. You can choose where to start as there are two different car parks. The Osprey car park is at the bottom of the hill and has facilities for getting changed, a cafe, and mountain bike hire.
If you are hiring a bike I would advise you book in advance as they do sell out. They were sold out the day we went but luckily we managed to hire in the nearby village Innerleithen. It wasn't too bad a mistake though, as we managed to stop for some much needed coffee at the coffee shop No.1. The second car park is called Buzzard's Nest and is slightly further up the hill so less uphill riding is needed to begin.
Spooky Wood descent was our longest route of the day at 1.5km downhill. The route is split up into a few sections by cross roads. These are useful for re-grouping and sharing how great the ride was. There is such an adrenaline rush on this route, heightened on our day as a there was low visibility from the snow. Even with four seasons in the one day, the centre is well equipped for it and the more mud the more fun.
